Zylon® PBO Fiber

Zylon® PBO

World’s Strongest Synthetic Fiber

History
PBO was first developed in the 1980’s and is the world’s strongest man-made fiber. It is also the first organic fiber whose cross-sectional strength outperforms both steel and carbon fiber.

Composition
Zylon® PBO is a rigid-rod isotropic crystal polymer that is spun by a dry-jet wet-spinning process.
